Yes Arbab is right they are not good container plant.i killed 2 of my double yellows last year.i have some in ground,they are doing very well.they are tropical plants.do well in moon soon.but hot summers & cool winters kill them in containers.

Experiments to grow them in smallest containers are going on.
According to them they can be grown in 10 inch container provided you cut off lower 2 inches of soil with roots every year. I have not tried it.
